IMPROVEMENT IN SILK AND THREAD MEASURING APPARATUS.

Specification forming part of Letters Patent No. 114,] 14, dated April25, 1871.

To all whom it may concern:

Be it known that I, LUOIUS DIMOCK, of Leeds,in the countyof Hampshireand State of Massachusetts, have invented a new and useful Improvementin Machines for Measuring Silk and other Threads; and I do herebydeclare that the following is a full, clear, and exact description,reference being had to the accompa.

nying drawing, forming part of this specification, and in which- Figure1 represents a side elevation, and Fig. 2 a plan, of a machineconstructed in accordance with my improvement. Fig. 3 is a view ofcertain portions of the driving devices detached, in illustration of anadjustable eccentric-bearing for keeping the driven wheel or pulley ofthe winding-spool in frictional contact with the driving-wheel.

Similar letters of reference indicate corresponding parts.

My invention consists in a certain arrangement of spool-spindles with ameasuring-wheel, round which the silk or thread is passed as it isunwound from one spool onto another, registering or counting wheelsoperated by screws and worm-wheels from the measuringwheel, as a driver,and adjustable on their shafts to set them in any required relation totheir index, and certain driving mechanism for setting in motion thewinding-spool, and which consists of a main or band wheel and innerpulley or wheel operating by frictional contact, preferably under aneccentric adjustment of its bearing, with the rim or band of the mainwheel, the whole forming a compact and advantageous arrangement ofdevices, which, combined, constitute a machine useful alike to thedealer and manufacturer, for testing or measuring the amount of silk orthread wound upon a spool or spools.

Referring to the accompanying drawing, A represents the frame of themachine, which frame may be of any suitable construction. B is the mainor band driving-wheel, arranged at the back or one side of the machine,and turning on a horizontal pivot or shaft, 1). The band or rim of thiswheel is made to project in front, and receives within it, at the oneend of the machine, a small friction wheel or pulley, G, mounted on aspool-windingspindle, c, that is fitted with loose or adjustablecentering friction-cones d d, for holding the windingspool D in betweenthem, and which is rotated by the frictional contact of the pulley Gwith the band-wheel D. To regulate the drivingfriction, as wear or othercircumstances may require, the spindle c is supported in an adjustableeccentric-bearin g, E, that may be turned, on slackening a set-screw, e,to bear the pulley G with more or less force up against the interior ofthe rim of the wheel B. Arranged below the spindle c, and parallel withit, is the spindle f, which carries, between adjustable friction orclamping and centering cones g, the spool F, the amount of silk orthread on which it is required to measure. Said spindle f is retained inits place or. centers by spring clip or hold, so as to admit of itsready removal and insertion for the placing of the spool on it to betested. Such spool F, when adjusted to its place, lies directly underthe winding-spool D.

Gr is the measuring-wheel, round a groove in which the silk or thread hfrom the spool F, running through a guide, '5, is passed, and the outerend of such silk or thread made fast to the winding-spool D, so that byrotating the latter through the band-wheel B and frictionpulley C saidsilk or thread is unwound from the spool F and wound on the spool D, andby its tension the measuring-wheel G kept revolving with a velocity dueto the travel of the thread, and its rotations or extent of travel madeidentical with the quantity or length of thread passing over it;consequently its measuring capacity is in no way affected by the size orvarying diameter of the spool or body of thread thereon to be measured.This measuring-wheel G is made fast to an independent spindle, k,arranged to occupy a parallel position with the spindles c and f at theopposite end of the machine, which spindle is has a screw, 1, on itsinner end, that serves, as the measuring-wheel G is rotated by thepassage of the thread over it, to give motion to a wormwheel, m, on aspindle, a, arranged to lie at right angles to the spindle 7c. andrunning crosswise of the driving-wheel B in front of it. Said spindle ncarries a counting or registering wheel, H, and serves, by a screw, 0,011 its end, and a worm-wheel, p, on a spindle, q, that lies in the sameaxial line, or thereabout, as the main wheel B, to give motion toanother registering wheel or disk, I. These registeringwheels are heldby friction on their respective spindles n and q, so that While they arerotated by said spindles they are adjustable or capable of beingindependently turned thereon to set them as required relatively to eachother and to a double index or pointer, J. Said wheels are divided andnumbered to express quantities as required, running from 0 upward-theone (registering-Wheel H) counting units in yards, and the other(registerin g-wheel I) tens, or such other relative divisions as themeasuring of the silk or thread may require.
